There are some drawbacks to consider. The noise level is rated at 60 dB, which could be noticeable, especially during quiet hours in residential areas. While it has a solid cooling capacity, it doesn’t come with an Energy Star rating, which may be a concern for some consumers focused on efficiency ratings. Furthermore, at 77 pounds, it may require more than one person for installation, particularly for those not accustomed to handling heavier appliances.

On the downside, the unit operates at a noise level of 52 dB, which might be audible in quieter environments, potentially distracting for some users. While it is equipped with modern features, it does not have an Energy Star rating, which could mean it may not be as energy-efficient as other models available on the market.
